The invention relates to machines forfapplying the paste to storage battery plates or grids, and has among its other objects the provision of a machine of the kind described that is ecient, durable, simple in construction, and has a large capacity.

Particular objects of the invention are to provide improved means for feeding battery grids into and through a machine of the kind described; to provide improved means for packing the paste into the grids, and to provide improved means for giving the pasted grids a finished appearance.

Many other objects and advantages v/ill appear as this description progresses, reference being had tothe accompanying draw.

Referring to the drawings wherein a preferred embodiment of the invention is illustrated, it will be noted that the improved machine comprises a frame l0 having a bed portion ll supported upon legs l2. Journalled in the frame is a main drive shaft 14 provided with asprocket Wheel l5 which meshes with a sprocket chain 16 threaded over a pinion 17 secured to the shaft of an electric motor 18 mounted underneath the the bed portion l1. A sprocket-Wheel 3l hxed to the shaft 26 meshes with a sprocketchain 32 which drives a sprocket-Wheel 3d fined to a shaft 3d rotatably journaled in the Wall or bracketl'members 30 (see .F ig. A. gear 35 hxed to the shaft 34: meshes With gears 37 and 38 which are rigidly secured to the shafts 39 and 40, respectively, the shafts 39 and 40 being rotatably journaled in the Wall or bracket members 30.

A pulley 42 mounted upon and constrained to rotate `with the shaft 26 drives a belt d3 which is trained over rolls t and d5 (see lilig. 3). lhe roll at is rotatably journaled in the bed portion 11 and the roll ll5 is rotatably journaled in bearing blocks el? `which are slidably journaled in the bed portion il and may be brought into adjusted positions to take up slack in the belt 4:3. Means for adjusting the bearing blocks 47 preferably comprises rods 50 whichV are screw-threaded through blocksl provided on the bed portion 1l, the inner ends of the rods 50 being svviveled to the blocks d?.

The roll 44 is driven by the belt d3 and it is employed to drive improved mechanism for feeding the battery grids into the machine. 'lhe feeding means preferably comprises disks 53 xed to the ends of the roll d4 and provided with crank-pins 5d which' are connected by links to downwardly entending arms 56 depending from a feeding plate. The feeding plate 57 is slidably jour naled in bracket members 58 which are pref erably formed integral with the bed portion ll. The plate 5'? rests upon rollers 59 journaled in the bracket members 58. Disposed above the plate 57 to hold it in position upon the rollers 59 are rollers 60 journaled in plates 61 secured to the bracket members 58. Y

` The plates 61 support a table 63 upon which battery gridsmay be stacked Aso that they may be manually fed into the feeding mechanism of the machine as required.

Mounted in front of the table 63 is a plate 65 adapted to support a pil-e or stack of the grids which are to be pasted `(see Fig. 1). The grids are preferably molded in pairs, as best illustrated in Fig. 7, the pairs being broken in two after the pasting operation. In the drawings, the grids are identified by reference character 6G. The plate 65 is preferably secured to the bracket members 58 by screws 68 and shims are preferably provided between the plate 65 and the bracket members 58 so that the plate may be adjusted vertically with respect to the plate 57. It is readily understood that when a stack of plates rests upon the plate 65 and the machiney is in operation, the plate 57 will reciprocate and at each forward stroke will engage the lowermost pair of grids and ad- Vance them to the pasting apparatus.

To insure proper placing of the grids upon the plate 65, an inclined guide-plate 70 is preferably securedto the plate 61 and positioned at the forward edge of the table 63. Then as the plates are fed pair by pair from the bottom of the stack, the plate 70 alines each pair-in turn with the forward edge of the feeding plate 57 so that it may be en gaged thereby when it advances toward the pasting apparatus. When the grids are placed upon the plate 65 they are preferably alined against a` vertically disposed plate 72 which has its lower edge space from thev plate 65 a distance sufficient to allow the grids to be advanced pair by pair to the belt 43 (see Fig. 3).

In the preferred embodiment of the invention, the' grids do not rest directly upon the belt 43, as a web 73 of paper is preferably advanced with the belt and rests thereon to support the grids. The web 7 3 is withdrawn from a. roll 74 mounted upon a shaft 75 which is rotatably journaled in slots 76 formed in the frame l0. (See Fig. l)

A crank shaft 77 has its ends journaled in the wall or bracket members 30 and is driven from the shaft 29 by a sprocket chain 78 (Figs. 8 and 9). The upper ends of links 79 are journaled on bearing portions of the crank shaft 77 and intermediate these bearing portions the crank-shaft is formed intol a paddle or blade 77 a adapted to agitate the material with which the grids are to be pasted. The lower ends of the links 7 9 are provided with bosses 79e which ride in vertical grooves 7 9b formed in the wall or bracket as shown in Fig. 8, but during its upward strokes the paddle is tilted in a nearly vertical position, as shown in Fig. l0. Stops 79e and 79f engageable with the links 79 limit the angular distance through which the paddle oscillates..v During its downward strokes the paddle tamps paste into the grids passing beneath it and during its upward strokes it assumes a position permitting it to slide through the paste with a minimum of resistance. Obviously, the paddle 79d feeds the paste downward toward the grids. Rolls 80, 81 and 82 are formed integral with, or are secured to the shafts 29, 34 and 40, respectively, and are disposed above the belt 43 to feed the paste to and pack it in the grids advanced by the belt43. The roll 80 is preferably provided with a plurality of angle irons 84 secured to its cylindrical surface, posed, as best shown in Figs. 2 and 6. This construction insures that a sufficient quantity of paste will be advanced to the grids.

Rolls 81 and 82 are provided with longitudinally extending grooves 86 and 87, respectively, upon their cylindrical surfaces, which grooves are bent at substantially the middle portions thereof, as best shown in Fig. 2. The roll 86 is rotated through the medium of vthe gear 35 in a clockwise direction (Fig.

so that thev lower surface thereof travels 1n a direction opposite ,to that in which the grids are advanced. "The roll 82 is driven through the medium of a gear 38 and is rod tated in a counter-clockwise direction so that its lower surface travels in the same direction as the grids.` It will be noted that the grooves 86 and 87 of the rolls 81 and 82, respectively, are bent in such manner that the ends of the grooves come in Contact with the advancing grids before the central portions thereof.

The rolls 80, 81 and 82 are disposed-between the wall or bracket members 30 which cooperate with an end wall 90 to form a hopper 91 which is not provided with a back wall.

It will be noted that paddles 77a and 7 9d are disposed between the rear wall 90 and the roll 80 so that the paddle 79d forces some paste into the grids before they reach the roll 80. Disposed in the rear end of the hopper 91 and posterior of the roll 82 is a roll 93 formed integral with, or rigidly secured to the shaft 29. The roll 93 is preferably formed from metal and is adapted to engage the upper surfaces of the grids as they are advanced by the belt 43 and to cooperate with the belt to pack the paste firmly in the grids and to polish and finish the upper surfaces thereof. The cylindrical surface of the roll 93 is preferably engaged by a scraper 93a mounted upon a cross-bar 936 secured to the wall members 30. This scraper removes superfluous paste from the roll 93 and insures that it will'have a relatively polished the angle irons being diagonally disessence surface adopted to im art e nished appearence to the upper sur ece of the grids.

As the grids pass from beneath the roii 93 they` ere preferably -engaged by e, Wiper nieniioer 9i formed from spring steel, or other suitehie materiei, the Wiper member 9i being secured to end positioned between the Weii or bracket members 30.
